Acute cholecystitis affects ∼200,000 individuals annually in the United States, with laparoscopic cholecystectomy as the gold standard treatment. However, in high-risk surgical candidates, alternative drainage methods are necessary. Percutaneous transhepatic gallbladder drainage (PT-GBD) has traditionally served as the primary alternative intervention, offering rapid decompression, but is limited by a negative impact on the patient’s quality of life, the risk of long-term or even permanent tube placement, adverse events, and high recurrence rates. Endoscopic approaches, such as endoscopic transpapillary gallbladder drainage (ET-GBD) and, more recently, endoscopic ultrasound-guided gallbladder drainage (EUS-GBD), have emerged as viable alternatives to PT-GBD. EUS-GBD, first introduced in 2007, offers technical and clinical outcomes comparable to PT-GBD with fewer adverse events, shorter hospital stays, and lower rates of recurrence. The introduction of lumen-apposing metal stents (LAMS) has revolutionized EUS-GBD, simplifying deployment and enabling subsequent internal gallbladder access, which allows additional interventions such as cholecystoscopy and stone removal. EUS-GBD is now supported by international guidelines, and 1 device has achieved FDA approval for the management of acute cholecystitis in nonsurgical candidates. Proper patient selection is essential, guided by multidisciplinary evaluation, with EUS-GBD contraindicated in specific scenarios such as gallbladder perforation, coagulopathy, and large-volume ascites. Technical considerations include choice of access site (transgastric versus transduodenal), stent type, and procedural route [direct (freehand) or wire-guided]. Postprocedural care and stent management remain variable and nonstandardized. Emerging data suggest that interval cholecystectomy can still be performed safely after EUS-GBD. As adoption of EUS-GBD with LAMS expands, structured training and standardization of practice are crucial to optimizing outcomes.

Introduction: There is an increasing interest in cold snare endoscopic mucosal resection (CS-EMR), and studies have shown its safety and efficacy for colonic polyps. This meta-analysis aims to assess the safety and efficacy of CS-EMR for the removal of duodenal adenomas. Methods: We conducted a comprehensive literature search of several databases, from inception through February 2023, for studies that addressed outcomes of CS-EMR for nonampullary duodenal adenomas. We used the random-effects model for the statistical analysis. The weighted pooled rates were used to summarize the technical success, polyp recurrence, bleeding, and perforation events. Cochran Q test and I 2 statistics adjudicated heterogeneity. Results: Six studies were included in the analysis. In all, 178 duodenal polyps were resected using CS-EMR. The pooled rates were 95.8% (95% CI 89.1–98.5%, I 2=21.5%) for technical success and 21.2% (95% CI 8.5–43.6%, I 2=78%) for polyp recurrence. With regards to CS-EMR safety, the pooled rates were 4.2% (95% CI 1.6–10.5%, I 2=12%) for immediate bleeding, 3.4% (95% CI 1.5–7.6%, I 2=0%) for delayed bleeding, 2.8% (95% CI 1.1–6.7%, I 2=0%) for perforation, and 2% (95% CL 0.5–7.5%, I 2=0%) for post-polypectomy syndrome. Rates were not significantly different for large adenomas. Three studies reported data on CS-EMR and conventional EMR. Compared with conventional EMR, CS-EMR had lower odds of delayed bleeding, OR 0.11 (CI 0.02–0.62, P value 0.012, I 2=0%). Conclusion: Our findings suggest that CS-EMR is a safe and effective strategy for the resection of nonampullary duodenal adenomas, with an acceptable recurrence rate. Data from larger randomized controlled studies are needed to validate our findings.

Background Cold snare endoscopic mucosal resection (CS-EMR) can reduce the risks associated with electrocautery during colon polyp resection. Data on efficacy are variable. This systematic review and meta-analysis aimed to estimate the pooled efficacy and safety rates of CS-EMR. Methods We conducted a comprehensive literature search of multiple databases, from inception to March 2023, for studies addressing outcomes of CS-EMR for colon polyps. The weighted pooled estimates with 95 %CIs were calculated using the random effects model. I2 statistics were used to evaluate heterogeneity. Results 4137 articles were reviewed, and 16 studies, including 2592 polyps in 1922 patients (51.4 % female), were included. Overall, 54.4 % of polyps were adenomas, 45 % were sessile serrated lesions (SSLs), and 0.6 % were invasive carcinomas. Polyp recurrence after CS-EMR was 6.7 % (95 %CI 2.4 %–17.4 %, I2 = 94 %). The recurrence rate was 12.3 % (95 %CI 3.4 %–35.7 %, I2 = 94 %) for polyps ≥ 20 mm, 17.1 % (95 %CI 4.6 %–46.7 %, I2 = 93 %) for adenomas, and 5.7 % (95 %CI 3.2 %–9.9 %, I2 = 50 %) for SSLs. The pooled intraprocedural bleeding rate was 2.6 % (95 %CI 1.5 %–4.5 %, I2 = 51 %), the delayed bleeding rate was 1.5 % (95 %CI 0.8 %–2.7 %, I2 = 18 %), and no perforations or post-polypectomy syndromes were reported, with estimated rates of 0.6 % (95 %CI 0.3 %–1.3 %, I2 = 0 %) and 0.6 % (95 %CI 0.3 %–1.4 %, I2 = 0 %), respectively. Conclusion CS-EMR demonstrated an excellent safety profile for colon polyps, with variable recurrence rates based on polyp size and histology. Large prospective studies are needed to validate these findings.

Abstract Background and study aims Splenic injury (SI) during colonoscopy is an underappreciated adverse event. Our aim was to examine the occurrence and outcomes of patients who developed SI after inpatient colonoscopy using a nationwide dataset. Patients and methods Retrospective, observational study using the National Inpatient Sample (NIS) between 2012 and 2018. All patients with ICD9/10CM procedural codes for colonoscopy with or without SI were included. The primary outcome was the association between SI and inpatient colonoscopy. Secondary outcomes were inpatient morbidity, mortality, resource utilization, splenectomy rates, hospital length of stay and total hospital costs and charges. Comparative analyses were performed between patients with and without SI. Multivariate regression analyses were utilized. Results A total of 2,258,040 of inpatient colonoscopies were included. Of these, 240 had associated SI and 25 patients required splenectomy (10.4 %). The incidence of colonoscopy-associated SI remained relatively stable between 2012 and 2018 (0.033 % versus 0.020 %, respectively). The mean age of patients with and without SI was 63.7 and 64.1 years, respectively. The occurrence of SI was calculated as 10.63 cases per 100,000 inpatient colonoscopies. Patients who had associated SI displayed significantly higher odds of inpatient mortality (aOR: 14.45) and ICU stay (aOR: 10.11) compared to those without SI. Conclusions Splenic injury confers significantly higher odds of inpatient mortality, and resource utilization. The incidence of SI related to colonoscopy remained stable during the study period. Although uncommon, SI should be considered when encountering patients with abdominal pain after colonoscopy.

Abstract Background and study aims With newer imaging modalities, indications for use of endoscopic retrograde cholangiopancreatography (ERCP) have changed in the last decade. Despite advances in ERCP, paucity in recent literature regarding utilization and outcomes of ERCP exists. Thus, the aim of this study was to assess the inpatient use of ERCP, outcomes, and most common indications. Patients and methods Retrospective-cohort study using the Nationwide Inpatient Sample 2007–2016. All patients with ICD9–10CM procedural codes for ERCP were included. The primary outcome was the use of ERCP. Secondary outcomes included determining procedural specifics (stenting, sphincterotomy and dilation), complications (post-ERCP pancreatitis [PEP], bile duct perforation), hospital length of stay, total hospital costs and charges. Multivariate regression analysis was used to adjust for confounders. Results A total of 1,606,850 patients underwent inpatient ERCP. The mean age was 59 years (60 % female). The total number of ERCPs increased over the last decade. Patients undergoing ERCP in 2016 had greater odds of undergoing bile duct stent placement, pancreatic duct (PD) stenting, biliary dilation, pancreatic sphincterotomy, PEP and biliary perforation. Inpatient mortality decreased. Hospital charges increased, while length of stay (LOS) decreased. Conclusions The number of ERCPs increased in the past decade. Odds of therapeutic interventions and complications increased. The most common principal diagnoses were choledocholithiasis and gallstone-related AP. Hence, physicians must be aware to promptly diagnose and treat complications. These findings may reflect the increased case complexity and fact that ERCP continues to evolve into an increasingly interventional tool, contrasting from its former role as a predominantly diagnostic and gallstone extraction tool.
